atrailer G
Risk of accident
When reversin gthe vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load R
the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents.
You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section.
i When towing atrailer, set the tyre pres-
sure on the rear axle of the towing vehicle
for am aximum load; see the tyre pressure
table in the fuel filler flap.
You will find installation dimensions and loads
in the "Technical data" section
(Y page 303).
The maximum drawbar load of the trailer
drawbar on the ball coupling is 75 kg. How-
ever, the actual noseweight must not exceed
the value given on the trailer tow hitch and
trailer identification plates. The lowest weight
applies.
! Use anoseweight as close as possible to
the maximum permissible noseweight. Do
not use anoseweight of less than 50 kg,
otherwise the trailer may come loose.
Bear in mind that the payloa dand the rear
axle load are reduced by the actual nose-
weight.
Please notet hat when towing atrailer, PARK-
TRONIC* (Y page 140) and Parking Guid-
ance* (Y page 143) are only availabl ewith
limitations ,ornot at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use atrailer with aheight-adjustable trailer
drawbar. 194
